Motor Vehicle Door Lock Authentication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle door lock devices are inconvenient as they require multiple operations for the driver to open the door, and passengers without a transmitter cannot open the door swiftly, leading to inefficiencies in access.
Innovation Solution
A motor vehicle door lock device with an integrated control system that authenticates user identity via wireless communication, enabling or disabling external switches based on the user's presence, allowing for single-action door opening by both drivers and passengers when authenticated, and preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door lock device requires authentication via transmitter for external electric element operation, then unauthorized access is prevented, but passengers without a transmitter cannot open the door conveniently
Solution Approach 1:
The external electric element is designed to serve multiple functions: it acts as an unlocking switch when authentication is required, and as a door opening switch when authentication is not required. This multi-functionality allows both drivers with transmitters and passengers without transmitters to use the same external electric element for their respective needs, resolving the contradiction between security and accessibility.
2Reliability
If the door lock device requires two operations (unlocking action and door-opening action) for drivers with transmitter, then access control is maintained, but the door cannot be opened swiftly
Solution Approach 1:
The unlocking function and door opening function are merged into a single operation through the external electric element. When the external electric element is operated, the control device determines whether to perform unlocking or directly enable door opening based on authentication status. This merging eliminates the need for separate unlocking and door-opening actions, allowing drivers to open the door swiftly in a single operation while maintaining access control.
3Ease of operation
If the external electric element is always enabled for door opening, then passengers can open the door easily, but unauthorized door opening from outside the vehicle cannot be prevented
Solution Approach 1:
The functionality of the external electric element is made dynamic rather than static. The control device dynamically adjusts the function of the external electric element based on real-time authentication status and door lock state. When authentication is successful, it enables door opening; when authentication fails or the door is locked, it prevents unauthorized operation. This dynamic control allows passengers to open doors easily when permitted while preventing unauthorized access.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances convenience by allowing single-action door opening for authorized users while ensuring secure access control, reducing the number of operations required and preventing unexpected door openings.
Implementation Method 1
an ID signal is authenticated through a wireless communication between a transmitter carried by a driver and an authenticating portion in the vehicle

AI summary
A motor vehicle door lock device includes an engagement mechanism that engages with a striker to hold the door closed; a positioned outside a vehicle; a locking mechanism that turns an unlock state for enabling the engagement mechanism to be released based on a door-opening action of the outside handle with a locking motor as a drive source and a lock state for making releasing impossible, a control that enables an operation of the switches when an external transmitter is authenticated and cancels it when it is not authenticated; and an electric release mechanism that can release the engagement mechanism regardless of a state of the locking mechanism by releasing a releasing motor as a drive source.
